Martensitic Steel Castings And Forgings For Mining Mill Parts

1. Introduction to martensitic steel castings and forgings

Luokuang Co., Ltd. specializes in producing wear-resistant castings in grinding equipment and spindle tiles and tows of various grinding machines. Its strong casting, forging, heat treatment and machine adding capabilities, strict quality and process control methods, perfect testing and experimental means, so that its production and development of all kinds of wear-resistant products enjoy a high reputation in China, and exported to overseas.

The microstructure of MS-Martensitic Steel is almost Martensitic structure. It can be achieved by hot rolling or cold rolling. Martensitic steel has high tensile strength, and its maximum strength can reach 1600MPa. It needs to be tempered to improve its plasticity, so that it still has sufficient formability under such high strength. It is the highest strength grade of commercial high strength steel plate at present. Usually can only use rolling forming production or stamping shape simple parts, mainly used to form the requirements of the car door anti-collision bar and other parts to replace tubular parts, reduce manufacturing costs.

2. Martensite castings and forgings stiffness correlation parameters

Type Main components(%) Processing temperature(℃) Technology processing Application
Martensitic stainless steel Chromium content 13%～18% Quench and temper Steam turbine blades (lower carbon), medical and surgical tools, measuring tools, springs, etc. (higher carbon)
Martensite precipitation hardening stainless steel 400～500℃ High temperature solution, quenching Chemical pressure vessel, aircraft structure
Martensitic heat resistant steel Chromium content 7.5%～20.5% 650～700℃ Tempering It is mainly used for valves, turbine blades, nozzles, bolts, etc
Maraging steel The content of nickel is 18% ~ 25%, molybdenum 5%, cobalt 8% and a small amount of titanium and aluminum 480℃ Solid solution of air cooling Rocket engine casings, aircraft landing gear, important molds

This kind of steel is in the Y-phase region at normal quenching temperature, but its Y-phase is stable only at high temperature, and the M point is generally about 300℃, so it is transformed into martensite when cooled.

This type of steel includes 2Cr13,2Cr13Ni2,3Cr13 and some modifications of 12% chromium hot strength steel, such as 13Cr14NiWVBA, Cr11Ni2MoWVB steel and so on. The mechanical properties, corrosion resistance, process properties and physical properties of martensitic stainless steel are similar to those of ferritic-martensitic stainless steel containing 12 ~ 14% chromium. Because there is no free ferrite in the structure, the mechanical properties of the steel are higher than those of the above mentioned steel, but the heat sensitivity of the heat treatment is lower.
